-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: glibc security update Advisory ID: RHSA-2010:0787-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0787.html Issue date: 2010-10-20 CVE Names: CVE-2010-3847 ===================================================================== 1. Summary: Updated glibc packages that fix one security issue are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 3. Description: The glibc packages contain the standard C libraries used by multiple programs on the system. These packages contain the standard C and the standard math libraries. Without these two libraries, a Linux system cannot function properly. It was discovered that the glibc dynamic linker/loader did not handle the $ORIGIN dynamic string token set in the LD_AUDIT environment variable securely. A local attacker with write access to a file system containing setuid or setgid binaries could use this flaw to escalate their privileges. (CVE-2010-3847) Red Hat would like to thank Tavis Ormandy for reporting this issue. All users should upgrade to these updated packages, which contain a backported patch to correct this issue. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 643306 - CVE-2010-3847 glibc: ld.so insecure handling of $ORIGIN in LD_AUDIT for setuid/setgid programs 6.
